UIWebview 加载空白页[关闭]

Question

我的表格视图包含文档列表，该列表在单击单元格时推送到网络视图，正确的文件路径从表格视图传递到网络视图，但网络视图加载空白页面。这是我使用的代码

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:@"ShowPDF"]) {
    NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];
    PDFViewController *destViewController = segue.destinationViewController;
NSFileManager *filemgr = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString* inboxPath = [documentsDirectory stringByAppendingPathComponent:@"Inbox"];
dirFiles = [filemgr contentsOfDirectoryAtPath:inboxPath error:nil];
destViewController.path = [documentsDirectory stringByAppendingPathComponent:[dirFiles  objectAtIndex:indexPath.row]];
}
} 

要加载 webview，我使用以下代码

- (void)viewDidLoad
{
    [super viewDidLoad];

   NSString *filePath =path;
   NSURL *url = [NSURL fileURLWithPath:filePath];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[pdfView loadRequest:request];
[pdfView setScalesPageToFit:YES];
   NSLog(@"%@", self.pdfView);

} 

需要帮助来解决此问题。

我解决了这个问题，下面这行有错误

destViewController.path = [documentsDirectory stringByAppendingPathComponent:[dirFiles  objectAtIndex:indexPath.row]];

换成下面一行

destViewController.path = [inboxPath stringByAppendingPathComponent:[dirFiles  objectAtIndex:indexPath.row]];
